# Find the terminal point P(x, y) on the unit circle determined by the given value of t. t = -4pi/3.

## Question:

Find the terminal point {eq}P(x, y) {/eq} on the unit circle determined by the given value of {eq}t {/eq}.

{eq}t = - \frac{4 \pi}{3} {/eq}

## Terminal Point on a Unit Circle:

The coordinates of points {eq}(x,y) {/eq} that correspond to a unit circle and whose center is located at point {eq}(0,0) {/eq} are tied to the sine and cosine values and the angle that represents the radius with the {eq}x {/eq}-axis. In this respect, the value of {eq}x {/eq} is associated with the cosine and the value of {eq}y {/eq} is related to the sine.
